Claims10
A method of preserving aqueous solutions or dispersions, said method comprising:
- providing an aqueous solution or dispersion comprising organic substances susceptible to degradation by anaerobically respiring microorganisms;
- adding to said aqueous solution or dispersion living microorganisms that inhibit the growth of said anaerobically respiring microorganisms in said aqueous solution or dispersion;
- whereby said added living microorganisms inhibit growth of said anaerobically respiring microorganisms and prevent degradation of said organic substances in said aqueous solution or dispersion, thereby preserving said aqueous solution or dispersion, said living microorganisms being Thiospaera pantotropha.
A method of preserving aqueous solutions or dispersions comprising glue or starch, said method comprising:
- providing an aqueous solution or dispersion comprising glue or starch substances that are susceptible to degradation by anaerobic bacteria in said solution or dispersion;
- adding to said aqueous solution or dispersion, living microorganisms that inhibit the growth of said anaerobic bacteria in said aqueous solution or dispersion, wherein said living microorganisms are added to said aqueous solution or dispersion in an amount of from 1 to 1010 microorganisms per kg of total organic carbon (TOC) of said glue or starch substances in said aqueous solution or dispersion, said living microorganisms being Thiospaera pantotropha;
- and
- adding at least one additive to said aqueous solution or dispersion, where said additive is selected from the group consisting of enzymes, supplines, surfactants, lignin sulfates, and combinations thereof.
